Abstract:

A simple modification to the currently utilized ACI model to estimate the axial capacity of rectangular reinforced concrete (RC) columns wrapped with FRP fabrics (sheets) is suggested. The modification accounts for the presence of longitudinally and transversely aligned FRP fabrics around the perimeter of the columns. The suggested model is based on the analyses of the experimental data available in the literature. Comparisons between the measured and estimated axial capacity of FRP wrapped columns show that the contribution of FRP fabrics in the column carrying capacity can be reasonably estimated using the modified model.
